<p>A vehicle movement control and detection system is divided into a plurality of vehicle control blocks, and the movement of a vehicle within a given vehicle control block is controlled by a vehicle control signal generated in the given vehicle control block. A signal receiver in the given vehicle control block senses the presence of a vehicle and a storage device stores a vehicle presence signal in response to the signal receiver sensing the vehicle presence. The storage device continues to store the vehicle presence signal until the vehicle has checked into the following vehicle control block. The generation of the vehicle control signal is prevented in the event the signal receiver no longer senses the vehicle's presence, or the storage device no longer stores the vehicle presence signal, during the time the vehicle is within the given vehicle control block, or in the event another vehicle is present in the succeeding vehicle control block.</p> |
